I ran Umbrel for over 2.5 years. I only ever had one issue. My SD card died. It was a quick and easy fix. I was back up and running fairly quickly.
Several months back, I built my own node from scratch because I wanted to do more and could no longer use a cookie cutter node.
For basic use, a Raspberry Pi 4 is fine, but it doesn't have the power that some need to do more.
